Final answer:
The Druksiai Lake is on the border between Lithuania and Belarus. Lithuania is the country that shares this border with Belarus, and it is the location of the largest lake in Lithuania.
Step-by-step explanation:
The country that has the Druksiai Lake on the border with Belarus is Lithuania. The Druksiai Lake, also known as Lake Drūkšiai, is the largest lake in Lithuania, and it lies in the northeastern part of the country, abutting the border with Belarus.
This region has seen significant historical changes, particularly after the dissolution of the Soviet Union in 1991, when countries like Belarus and Lithuania gained their independence.
Unlike Lithuania, Belarus has maintained a closer relationship with Russia and has faced challenges in democratization and integration with European structures, such as the European Union (EU).
